fertile week 😬

Breanna • Trying for #1 rainbow baby 🌈 🌈🌈🤰🏾
Soo I'm fertile this week and my predicted ovulation day is "March 24" but my glow is saying that if I do it today I have a 33% chance of BFP . My husband and I have been TTC for about 3 years . So I need advice on how accurate this calendar is. Thanks!
